University of Toronto researchers find that chlorine helps improve organic light-emitting diodes

China Education Equipment Purchasing News: The recent "Science" journal published the results of research scholars at the University of Toronto in Canada, saying that chlorine helps improve organic light-emitting diodes.

According to the news, under the guidance of Professor Zheng-Hong Lu, researchers Michael Helande and Zhibin Wang of the Department of Materials Science and Engineering at the University of Toronto have invented a method that simply uses chlorine gas to reduce the complexity of traditional OLED devices. Significantly improve its efficiency. The researchers have developed an ultraviolet auxiliary device that can oxidize the surface of indium tin oxide (ITO), the industry standard electrode material currently used in flat panel displays, by adding an atomic thickness of chlorine thin plate to establish an effective power supply. The medium of transmission. There is no need for multi-layer processing like traditional OLED, reducing equipment, production steps and costs.

The results also found that at a brightness of 10,000 candles per square meter (10000 cd / m2), the green-emitting Cl-OLED achieved a luminous efficiency of up to 50%, which is more than twice the efficiency of traditional OLEDs.
